摘要

朗沃斯活捕器被广泛用于捕获老鼠大小的啮齿动物和鼩鼱。然而，它们有许多缺点:一些有制造缺陷，导致灵敏度降低;体型较小的鼩鼱可以从踏板下通过，避免被捕获;被捕获的动物可以啃咬侧壁的特定部分，从而降低陷阱的耐用性。为了提高捕捉小鼩鼱的效率，我们在朗沃斯活陷阱的踏板上增加了一个可移动的锡斜坡，并使用了洗衣机来改进设计。为了修复和保护被捕获动物损坏的陷阱，我们使用了锡片。改进后的捕鼠器捕获小鼩鼱的效果明显优于原捕鼠器(Sorex caecutiens Laxmann, 1788; Sorex minutus Linnaeus, 1766)。锡片可靠地保护活陷阱免受动物的进一步破坏，并且不影响其捕获效率。

Modifications of Longworth traps to prevent wear and improve catchability of shrews (Sorex spp.)

Abstract Longworth live traps are widely used for trapping mouse-sized rodents and shrews. However, they have a number of disadvantages: some have a manufacturing defect, resulting in reduced sensitivity; smaller species of shrews can pass under the treadle, avoiding capture; captured animals can gnaw specific parts of the sidewalls and decrease the durability of the traps. To increase the efficiency of catching small shrews, we added a movable tin ramp to the treadle of the Longworth live traps and used washers to improve the design. To repair and protect traps damaged by captured animals, we used tin patches. The modified traps were shown to be significantly better than the original traps in catching small shrew species (Sorex caecutiens Laxmann 1788, Sorex minutus Linnaeus, 1766). Tin patches reliably protected live traps from further damages by animals and do not affect their catching efficiency.

期刊介绍： Mammalia is an international, multidisciplinary, bimonthly journal devoted to the inventory, analysis and interpretation of mammalian diversity. It publishes original results on all aspects of the systematics and biology of mammals with a strong focus on ecology, including biodiversity analyses, distribution habitats, diet, predator-prey relationships, competition, community analyses and conservation of mammals. The journal also accepts submissions on sub-fossil or recently extinct mammals.
